ADAMS started in sports at TEXAS football site ORANGEBLOODS.COM and in radio with CHIP BROWN and DAVID ANDERSON at then-Sports KZNX-A (1530 ESPN)/AUSTIN, and later worked for ESPN's LONGHORN NETWORK and ESPN; he joined THE ZONE in 2014 and co-hosted the morning show with BROWN. He also wrote two motivational books.

BROWN wrote on the ZONE website, "My heart is broken today. Hearts are broken all over AUSTIN and beyond.... SEAN had an undying love for sports and walked away from corporate world to pursue that love.... SEAN and I were preparing to fly to LOS ANGELES THURSDAY night for the TEXAS-USC game when I learned of his apparent heart attack. I was devastated. I raced to the hospital and refused to believe he was gone. I couldn't breathe, couldn't think. SEAN lost his dad to a stroke, and I lost my mom to pancreatic cancer. We talked about our love for our lost parents a lot.

"I can hear SEAN telling me - right now! - how important it is to reach out to loved ones all the time to tell them how much you love them and care about them. 'It's not enough to think it, CHIP,' he would tell me. 'Pick up the phone and say it out loud.' I'm saying it out loud right now - and I know you can hear me SEAN - 'I love you.'"
